Check all fans On M/board to see if they are working also that your heat sink on CPU is clean no fluff or dirt clogging vanes this could be an overheating problem
Another quick check is to remove side of case if it stays on longer it definitely is overheating

My Desktop E-machine EL1331G-01w turned itsself off during an update and now it will not come back on, it powers on then goes back off after a matter 2-5 seconds. What causes this?


Have someone check the cooling fan for CPU and power supply. If the unit have a blown cooling fan on the CPU it will do as you described. Will also do the same if power supply is no good. Boot into safe mode and see if it still shuts down.

I have a IBM net vista and the power button does not work


That IBM Netvista should have a model number on the back.

This tells me if the computer is so old it uses an AT power supply, or an ATX power supply; as modern computers do.

http://www.playtool.com/pages/psuconnectors/connectors.html#oldpc

The old AT form factor of Power Supply, used the above type of main power cables.

The Power On switch was usually connected to the Power Supply.
A separate cable went from the front of the computer, connected to a Power On button, to the Power On switch on the Power Supply.

Or a separate Power On switch was mounted to the Power Supply, and a metal rod pushed against it.
The metal rod pushed by a plastic Power On button, in the front of the computer.

The ATX form factor design uses a Soft Power On circuit.

When a Power Supply is plugged into power, there is a constant 5 Volts present.
The 5 Volt Standby Power.

The ATX power on switch is a Momentary Contact Switch.
Pressing it closes the Soft Power On circuit -> Temporarily.

The 5 Volt Standby power is re-routed, and 'excites' the Power Supply, which turns it on.

THIS type of ATX power on switch is common.
It is inside the plastic Power On button assembly,

Pc turns it self on by it's self


Make sure the power button isn't sticking at all. If it is sticking then use some glass cleaner on a cotton swab and clean around the button.
Try plugging the computer directly into a wall outlet instead of a surge protector or power strip to rule out a faulty product.
If the same thing keeps happening then you'll need to replace the power supply.

Dell inspiron 5150 do not come on when the power button pressed


If you remove the battery and disconnect power cord, then hold power button for 20 seconds, then reconnect power cord but do not re-insert battery, and the unit powers on okay, the problem may be your battery. If there is still an intermittent problem, the power connector inside the unit may be loose and need re-soldering, or you could have a bad power supply.

Left side don't play/ right side is perfect


You sound like you have a wire connection problem but to find out try using a spare pair of speakers or try headphones. Try to rule out any wierd system problem, but I don't think that is your problem. Since this problem went away and then came back reduces the likely hood that it is a power issue so I would go with wiring issues or connection problems. While you are playing music. Move the cable, bend it, and reinsert it a few times. Give the cable a work out. If it comes back while this is happening, you have an open connection. You will need to replace the speaker wiring.

can you be more specific when describing the computer 'struggling to restart'? Does it beep? Does it take several attempts to restart?
